Microsoft is planning to make the SkyDrive update available starting later today (June 20), officials said.

I'm thinking that Microsoft is relaunching SkyDrive today because the company is ready to make "Mango," the next version of its Windows Phone operating system, available to testers, starting this week. Microsoft officials have said that improved SkyDrive integration will be one of the new features in Mango. With Mango, users will be able to share photos stored on SkyDrive via e-mail, text or instant messaging, and will be able to share videos immediately after shooting them, with the uploading happening in the background, officials noted again today.

Update: One of my Twitter buds, @spatacoli, notes that "in the new SkyDrive you can click on the link 'View Synched Folders' and it'll show the folders synched with Windows Live Mesh." And there it is!
